(iv) Repeat the process of removing the open middle thirds of the remaining line segments
infinitely many times.

(a) Find the total length of the intervals removed from [0, 1] after three iterations, i. e. the
total length of the intervals removed from [0, 1] to get I3.
(b) By considering a suitable series, show that the total length of all of the intervals removed
is equal to 1.
(c) Despite the fact that an infinite number of intervals of total length 1 have been removed
to construct C, there are points in the interval [0, 1] that will never be removed, i.e. there
are points in C. What is one such point?
